Computer simulations have become an integral part of the engineering design process, offering a cost-effective means of performing 'what-if' analyses. This approach has gained acceptance alongside experimental methods. By leveraging mathematical modelling and analysis, researchers can explore various scenarios and optimize outcomes. In the context of medical therapy, computer simulations can be used to model patient responses to different treatments, allowing for more informed decision-making. This synergy between computer simulation and medical therapy holds great promise for improving patient care and outcomes.
